I have 153K on my 1996 single-cab, short bed Z71. It sounds like many people with this many miles have already replaced both the engine and transmission, I'm worried/wondering how much longer I have on both.

I am at 185K on my 97 with a 5.0 and the same tranny. Truck runs great still, no problems. I do believe yours is a vortec motor, so watch the intake gaskets, they like to leak. First sign of this would be unexplainable coolant loss.

262,000 on original motor and tranny. Properly maintained since purchased. As long as you take care of it, it will take care of you. I'm convinced!
